To measure the total number of digital tech jobs across the economy, we used data from the Office for National Statistics (ONS) Annual Population Survey (APS). This is a survey-based sample of the UK population – on individual people rather than businesses. To get UK-wide data on people working in tech jobs from the survey, we have to make sure that the sample of people reflects the broader UK population – so we have to use multipliers from the ONS.
But this kind of analysis does not measure the number of direct jobs created by digital tech companies. To understand the impact and benefits of digital tech we need to have reliable data not only on the number of tech jobs across the economy but also jobs, performance and productivity indicators for the sector itself.
To do this, we use official data from the ONS Business Structure Database (BSD), which we also use to look at the performance of tech companies. This methodology allows us to have refined data that can be relied upon as the most accurate count of direct jobs created by the digital tech companies across the country.
The numbers are quite different in some cases. This is because one analysis looks exclusively at people working for digital tech companies, while the other looks at people working in tech jobs across the economy.
This year, we have expanded the way we look at jobs for a few reasons, here is a run through of our thinking, and how the data we present is more robust and representative than ever:
This year we are presenting two different sets of stats on employment. This means that the economy-wide numbers should not be compared to the sector-wide ones. But we have used this year’s method to look back over time. If you want to compare employment in your local area, all the data you need is in the 2018 report.
The new 2018 analysis is based on a comprehensive look at all UK businesses that are PAYE or VAT registered. This means that using BDS data will provide us not only with the number of direct jobs created by tech companies but also helps us understand the performance of these companies. Viewed together, the two sets of data will help us understand all people working in digital tech.
The data on digital tech companies also contains financial information, as well as employment. This means that we can have reliable data on productivity. To get a true picture of jobs in digital tech, we need to look at performance, as well as quantity of jobs – this cannot be obtained from the APS alone.
